The demographic transition model consists of five stages:
Low-growth stage :high birth rate and high death rate lead to a population that varies over time, with little long-term population growth.
High-growth stage:high birth rate and declining death rate lead to sustained and significant population increase.
Moderate-growth stage:declining birth rate combined with already low death rate lead to continuing population growth.
Low-growth or stationary stage: low birth rate and low death rate lead to a very low rate of growth.
Declining population: very low birth rate and low death rate lead to decreasing population.
“The transition in the demographic transition occurs in stages 2 and 3, when death rates decline and then birth rates decline. When the death rate and birth rate fall, the country transitions from a high growth rate to a low or sustained growth rate. “ textbook Human Geography: People, Place, and Culture De Blij, page 52.
Further break down:
Stage 1:
Epidemics and plaques keep death rates high
Famines
Stage 2:
Population explosion (less deaths, birth rates still high)
Life improvement : ex. Industrial Revolution
Stage 3:
Continuing decreasing death rates, birth rates also decline
Greater urbanization, wealth, medical advances
Women delay marriage and child bearing
Contraceptives and abortion
Stage 4:
Low TFR
Women are the most educated and involved in the labor force
